CONTINUOUS MIXER.

Specification of Letters Patent.

Application filed March 29, 1917. Serial No. 158,222.

peditiously, thoroughl and comparatively inexpensively mixing uids orsemi-fluids of which grease, aint, soap, and an emulsion of asphalt andsoap, miscible in water, are examples.

The invention will be claimed at the end hereof, but will be firstdescribed in connection with the embodiment chosen from otherembodiments of it, for illustration in the accompanyin drawings in whichFigure 1,is an e evational View, principally in central section, of acontinuous mixer embodying features of the invention.

Figs. 2 and 3, are respectiv ely a longitudinal section and an end view,drawn to an enlarged scale, of the mixing nozzle shown in Fig. 1, and

Fig. 4, is a transverse sectional view of the casing shown in Fig. 1.

In the drawings 1, is a closed casing having an outlet 2, at or near oneend thereof.

3, is a choke-plate arranged in the casing and having through it arestricted passa e I 4. 5, is a mixing nozzle arranged in t e casing andprovided with restricted passages and with inlets 7, connecting thesepassages 6, with a manifold 8. 9, is a me-' chanical conveyer arrangedin the casing and having its spiral flights 10, and driving means 11,arranged and operated to feed away from the outlet 2. 12, are bafllesarranged on the inner wall of the casing. 13, 14 and 15, are pressurefluid feeds having spaced communication with the casing 1.

16, are pumps driven from the conveyor.

shaft b gearing 17, and adapted to su ly pressurl; for the feed. I havedescr iged the particular embodiment of the machine shown in thedrawings, but it must be understood that in some cases certain of thedescribed parts may be omitted or duplicated according to the number andcharacter of the materials to be mixed.

For the sake of a further description of the invention I will describethe operation of the machine in connection with an emuls1on of asphaltand soap miscible in water, but in so doing I do not intend to limit themachine to that use, or in any way other than as the appended claims mayrequire.

Asphalt is introduced at 14:, soap at 13, and water at. 7 and 15, underthe pressure of the umps 16, and in such manner that the casmg 1, iskept full and the operation is continuous. The fluid or pump feedoperates in opposition to the mechanical conveyer 9, and in oppositionto the choke plate 3, and the mixing nozzle 5, and the productthoroughly mixed is delivered continuously at 2. .The choke plate 3,when present, not only promotes the mixing operation, but also insuresthe mixture of asphalt, at first, with comparatively little soap andthereafter with more asphalt. The function of the mixing nozzle 5, whenpresent, is to thoroughly and intimately mix water with the previouslymixed asphalt and soap.

Obviously modifications may be made in details of construction andarrangement and hence the invention is not limited to those 7 matters orin any way other than the rior Patented Nov. 6, 1917.-

the same to the outlet against the opposition of the mechanicalconveyer.

2. A continuous mixer comprising the combination of a closed casinghavin an outlet at or near one end thereof, a c oke plate in the casing,a mechanical conveyer 1n the casing arranged to feed away from theoutlet, and a pressure fluid feed communicatin with the casing forkeeping the easing fulfof fluid and feeding the same to the outletagainst the opposition of the mechanical conveyer and of the chokeplate.

3. A continuous mixer comprising the combination of a closed casinghaving an outlet at or near one end thereof, a mixing nozzle in thecasing, a mechanical conveyer in the casing arranged to feed away fromthe outlet, and a pressure fluid feed communicating with the casing forkeeping the casing full of fluid and feeding the same to the outletagainst the opposition of the mechanical conveyer and of the mixingnozzle.

4. A continuous mixer comprising the combination of'a closed casinghavin an outlet at or near one end thereof, a c oke plate in the casing,a mixing nozzle in the casing, a mechanical conveyer in the casingarranged to feed away from the outlet, and a pressure fluid feed.communicating with the casin for keeping the casing full of fluid andeeding the same to the outlet against the opposition of the mechanicalconveyer and 1of the choke plate and of the mixing nozz e.

5. A continuous mixer comprising the combination of a closedcasinghaving an outlet at or near one end thereof, a mechanical conveyer inthe casing arranged to feed away from the outlet, and pressure fluidfeeds having spaced communication with the casing for keeping the casingfull of fluid and feeding the same to the outlet against the oppositionof the mechanical conveyer.

6. A continuousgmixer comprising the combination of a closed casinghaving an outlet, and means for feeding fluids under pressure into thecasing, the relation of the feeding means and the outlet being such.that the casing is kept full, and devices for emulsifying the fluidwhile under'pressure in the casing.
